Class ConnectionSet

    java.lang.Object
      |
      +--org.jgraph.graph.ConnectionSet

All Implemented Interfaces:
  Serializable

public class ConnectionSet
extends Object
implements Serializable

An object that represents a set of connections. Connections are equal, if equals returns true. Connections that are added later replace earlier connections.

  Serialized Form

Nested Class Summary
`static class` | `ConnectionSet.Connection` Object that represents the connection between an edge and a port.

Field Summary
`protected Set` | `connections` Contents of the connection set.
`protected Set` | `edges` Set of changed edges for the connection set.

Constructor Summary
`ConnectionSet()` Constructs an empty ConnectionSet.
`ConnectionSet(Edge edge, Port port, boolean source)` Constructs a ConnectionSet with one Connection.
`ConnectionSet(Edge edge, Port source, Port target)` Constructs a ConnectionSet with two Connections (to the source and target port of the edge).

Method Summary
`void` | `addConnections(CellView[] views)` Adds the connections in `views` to the connection set.
`ConnectionSet` | `clone(Map map)` Creates a new connection set based on this connection set, where the edges, and ports are mapped using `map`.
`protected static void` | `connect(ConnectionSet cs, Object edge, Object port, boolean source, boolean disconnect)` Connect or disconnect `edge` from `source` and `target` in `cs` based on `disconnect`.
`void` | `connect(Object edge, Object port, boolean source)` Connect `edge` to `port`.
`void` | `connect(Object edge, Object source, Object target)` Connect `edge` to `source` and `target` in the connection set.
`Iterator` | `connections()` Returns an `Iterator` for the connections in this set.
`static ConnectionSet` | `create(GraphModel m, Object[] cells, boolean disconnect)` Returns a connection set that represents the connection or disconnection of `cells` in `model` based on `disconnect`.
`void` | `disconnect(Object edge)` Disconnect `edge` from `source` and `target` in the connection set.
`void` | `disconnect(Object edge, boolean source)` Disconnect `edge` from `port`.
`Set` | `getChangedEdges()` Returns a `Set` for the edges in this connection set.
`Set` | `getConnections()`
`Set` | `getEdges()`
`boolean` | `isEmpty()` Returns `true` if the connection set is empty.
`void` | `setConnections(Set set)`
`void` | `setEdges(Set set)`
`int` | `size()` Returns the number of (edge, port)-pairs.

Field Detail

### connections

    protected Set connections

  Contents of the connection set.

### edges

    protected Set edges

  Set of changed edges for the connection set.

Constructor Detail

### ConnectionSet

    public ConnectionSet()

  Constructs an empty ConnectionSet.

### ConnectionSet

    public ConnectionSet(Edge edge,
                         Port port,
                         boolean source)

  Constructs a ConnectionSet with one Connection.

### ConnectionSet

    public ConnectionSet(Edge edge,
                         Port source,
                         Port target)

  Constructs a ConnectionSet with two Connections (to the source and target port of the edge).

Method Detail

### create

    public static ConnectionSet create(GraphModel m,
                                       Object[] cells,
                                       boolean disconnect)

  Returns a connection set that represents the connection or disconnection of `cells` in `model` based on `disconnect`.

### connect

    protected static void connect(ConnectionSet cs,
                                  Object edge,
                                  Object port,
                                  boolean source,
                                  boolean disconnect)

  Connect or disconnect `edge` from `source` and `target` in `cs` based on `disconnect`.

### addConnections

    public void addConnections(CellView[] views)

  Adds the connections in `views` to the connection set.

### connect

    public void connect(Object edge,
                        Object source,
                        Object target)

  Connect `edge` to `source` and `target` in the connection set. The previous connections between `edge` and its source and target are replaced in the set.

### connect

    public void connect(Object edge,
                        Object port,
                        boolean source)

  Connect `edge` to `port`. `source` indicates if `port` is the source of `edge`. The previous connections between `edge` and its source or target in the set is replaced.

### disconnect

    public void disconnect(Object edge)

  Disconnect `edge` from `source` and `target` in the connection set. The previous connections between `edge` and its source and target are replaced in the set.

### disconnect

    public void disconnect(Object edge,
                           boolean source)

  Disconnect `edge` from `port`. `source` indicates if `port` is the source of `edge`. The previous connections between `edge` and its source or target in the set is replaced.

### isEmpty

    public boolean isEmpty()

  Returns `true` if the connection set is empty.

### size

    public int size()

  Returns the number of (edge, port)-pairs.

### connections

    public Iterator connections()

  Returns an `Iterator` for the connections in this set.

### getChangedEdges

    public Set getChangedEdges()

  Returns a `Set` for the edges in this connection set.

### clone

    public ConnectionSet clone(Map map)

  Creates a new connection set based on this connection set, where the edges, and ports are mapped using `map`. If a port is not found, the old port is used. If both, the edge and the port are not in `map`, the entry is ignored.

  Note: Consequently, unselected edges are only reconnected at the first "paste" after a "cut", because in this case the ConnectionSet is not cloned.

### getConnections

    public Set getConnections()

  Returns:

### getEdges

    public Set getEdges()

  Returns:

### setConnections

    public void setConnections(Set set)

  Parameters:
    `set` -

### setEdges

    public void setEdges(Set set)

  Parameters:
    `set` -
